OVERVIEW: 57mm rockets are unguided air-to-ground or ground-to-ground munitions designed for suppression, area denial, and light anti-armor roles. They are typically used in pods mounted on helicopters, aircraft, or light ground vehicles to engage infantry, soft-skinned vehicles, and lightly fortified targets.

DETAILS: The 57mm rocket features a solid-fuel propulsion system and a high-explosive fragmentation warhead. These rockets are usually fired in salvos from multiple-launch pods, saturating target areas with explosive force and fragmentation. Due to their relatively small size and weight, platforms can carry large quantities, enabling sustained fire missions. The rocket is spin-stabilized and unguided, relying on volume of fire for effectiveness rather than precision. It is widely used in asymmetrical warfare and close air support roles.

ROLE SUMMARY:
